EqMac
eqMac is a system-wide audio equalizer and volume mixer for macOS. It utilizes a virtual audio driver to intercept system output, allowing users to adjust frequency response, boost system volume, and control independent volume levels for different running software applications.
The project functions as an audio unit plugin host, integrating third-party plugins into the system audio stream for professional effects. It also includes a local web server that enables remote audio control via HTTP, allowing users to modify audio parameters from a mobile device or other external hardware on the same network.
Additional capabilities include real-time spectrum analysis, the application of specific headphone frequency profiles, and spatial audio simulation. The software supports independent stereo channel equalization, audio routing to virtual outputs for recording, and the ability to render processed audio to files.
User configurations and presets can be synchronized across devices via cloud storage, and application functions can be mapped to customizable system-level hotkeys.
